Allergic effects of the residual monomer used in denture base acrylic resins
Denture base resins are extensively used in dentistry for a variety of purposes. These materials can be classified as chemical, heat, light, and microwave polymerization materials depending upon the factor which starts the polymerization reaction. Their applications include use during denture base construction, relining existing dentures, and for fabrication of orthodontic removable appliances....
متن کاملDiffusion of residual monomer in polymer resins.
A simplified mathematical model which made use of Fick's laws of diffusion written in spherical coordinates was developed to describe the rate of diffusion of residual monomers from polymer resins. The properties of the monomer-polymer system which influenced the amount of monomer remaining in the polymer as a function of time were the diffusivity and solubility of the monomer in the polymer, a...
متن کاملThe evaluation of residual monomer released after polymerization of four different composite resins
Purpose: The aim of this study is to compare the amount of Bis-GMA, UDMA, and TEGDMA released from four different types of composite resins in three different time periods using the HPLC device. Materials and Methods: Four different composite resin materials with nanofiller content were used in the study. A total of 40 sample discs were prepared and polished to provide 10 pieces for each mater...

AA and its esters are unlikely to persist in the environment. Acrylates have medium to high mobility for adsorption and desorption to soils. They are not expected to bind to soil or sediment. If released to air, they will undergo photo-degradation within days. AA and all of the esters are readily biodegradable except t-BA, which is inherently biodegradable. In contact with water, abiotic hydrol...
